Application filed February 5, 1925. Serial No. 7,069.

This invention relates to spinning machines. It is common, in the art of spinabove named ning artificial silk from cellulose solutions, to discharge the cellulose solution from spinnarettes into an alkaline bath and to lead the threads which are set or solidified by said bath over suitable guiding elements and,

to centrifuges where the plurality of threads discharged from the spinnarettes are twisted together by the action of the centrifuges.

It is a primary object of the present inventionto provide a new and improved assemblage of parts adapted to carry out the functions in a facile and eflicient way.

A further object of the invention is to provide an improved motor mounting for the motors which drive the centrifuges.

A further object of the invention is to provide an improved means for rendering said motors self-oiling.

Further objects and advantages of the in-' vention will be set forth in the detailed de- .scription which follows.

Figure 7 1s a sectional view through one of the guide tubes, hereinafter described.

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring now to the drawings, 5 designates the base portion of a frame which includes-longitudinally extending angle irons 27. The gear wheels 26 and 27 have smaller through a number -of very minute openings. I

formed in the spinnarettes 10. These spinnarettes are carried by tubular arms 11 which are of a usualand well known construction and receive their supply of the cellulose solution through pipes 12 and flexible connections 13. These connections and the rotary feed pumps for the solution, indicated at 14, are also of a usual and known construction. The pumps are driven b gears, indicated at 15 and 16, from longitudinally extending shafts 17. The main drive shaft of the machine is indicated .at

.18. This shaft carries a driving pulley 19 and an elongated pinion 20. A large gear wheel 21 which meshes with the pinion 20 is mounted upon a shaft 22 and this shaft 22, in turn, carries a gear wheel 23 which meshes with a gear wheel 24, upon the shaft 25. The gear wheels 23 and 24 are of the same size and mesh with gear wheels 26 and gear wheels 28 and 29 afiixed to them to turn with them and gears 26 and 28 and 27 and 29 are respectively mounted upon stub shafts 30 and 31 mounted in slots 32 of movable brackets 33. -The-position of the brackets themselves, may be adjusted, since they are ivoted to move about the axes constituted by shafts 17 and are provided with arcuate extensions 34. having arcuate slots 35 formed therein for the passage of suitable binding elements 36, which project from the eyes 37, of fixed brackets 38. Only the left hand bracket 33 has been illustrated, the right hand bracket 33 has been omitted to more clearly show the bracket 38 lying behind the same. The gear wheels 28 and 29 mesh with shafts 17.

The reason for mounting the stub shafts 30 and 31 in adjustable brackets, such as 33,

gear wheels 39 and 40 on the is to permit of the substitution of gears of I gear wheel 49.

,ciprocation is imparted by another size at this point, when desired, to thereby vary the discharge rate of the metering feed pumps 14. It is common practice and merely a matter of mechanical skill to mount gears in this fashion and for the purpose indicated, construction of this sort being common in lathes and many other mechanical devices. The elongated pinion 20 (Figure 4) also meshes with a gear wheel 41 "upon a horizontal shaft 42. The shaft 42 carries a bevel pinion 43 which meshes with a bevel pinion 4-4 on the lower'end of an upright shaft 45. Beveled pinions 46 and 47 transmit motion from the shaft 45, to a horizontal shaft 48. This shaft carries a gear wheel 49 (Figure 1) and a pinion 50. The pinion 50 meshes with a gear wheel 51, upon a. longitudinally extending cam shaft 52, while the gear wheel 49 meshes with a gear wheel 53 upon a longitudinally extending shaft 54 constituting one of the godet wheel drive shafts. The othergodet wheel drive shat is driven by a gear wheel 56 and an interposed idler gear 57 from the The godet wheel drive shafts 434 and carry beveled pinions 56 and 5'7, which mesh with beveled pinions 58 and 59 upon the obliquely disposed godet wheel shafts 61.- The latter shafts are mounted in bearing brackets 62, which are in turn clamped by bolts 63 to longitudinally extending channel irons 64 that are suymorted'upon the standards 7. Only one of the standards 7 has been illustrated, but it is to be under stood that as many of these standards will be employed as the length ofthe machine may justify. It will be noted that the machine comprises. a large number of spinning units. some of which are disposed upon one side of the machine and some of which are disposed upon the other side of the machine. and there may be as many of these combined in a single machine, as is desired.

Each spinning unit comprises a centrifuge. and since they are all alike a description of one will serve as a description of all. Each centrifuge comprises a rotative bowl or pot 66. the base of which. indicated at 67. has

frictional engagement with a disc 68 to which rotation, at high speed. is imparted by an electric motor 69. The several centrifuges are mounted in longitudinally extending housings 70.

The plurality of threads discharged in parallel from the orifices of the spinnarett-cs are led, in their parallel relation. over the godet wheels indicated at 71, and thence to the guide tubes 72, to which vertical retravcrse rods 73. These traverse rods pass through guides 7 4 of the brackets 62 and have vertical reciprocation imparted to them by rock arms 75. These rock arms are pivoted at 76 and their outer ends have pivotal engagement with the caps 7 7 upon the upper ends of the traverse rods.

The necessary upward movement is imparted to the traverse rods by cams 78-ot cam shaft 52, said cams acting against the tails 79 of the rock arms 75.

The action of the centrifuges in twisting the threads together is well known in the art and is not peculiar to this invention. It suffices to say that the thread passing through the guide tubes 72 thrown outwardly by centrifugal force and against the walls of the pots 66 and that the action of the pots in carrying the thread aroundflat a high rate of speed results in twisting the threads together about the axis constituted by the center of the guide tubes is illustrated upon an enlarged scale in Figure 7. These tubes are of substantially ,the same construction as those heretofore employed except that from the lower-most restricted portion of the tube, indicated at Figure 8. the tube flares outwardly in bell formation at 81 upon a grad ual curve, so' that the thread is, at no time, bent to a sharp angle but leaves'thetube at such angle that damage to the tender threads is eliminated.

The pots" 66' have small openings .66

formed in them through which the caustic soda. or like solution, may be thrown from the pots by centrifugal force into the housings from which it is conducted by means of ducts 82 to a collecting tank 83, see Fig ure 3.

An overflow pipe 84 serves to maintain the solution in tank 8 at a determined level, said overflow pipe discharging into collect ing tank 83. i

, \Vhile the tank' 8 extends the full length of the machine, the several spinnarettes may be disposed in more or less individual com:

.partments of said tank, by placing partitions 8 (Figure 4) across thetank at intervals and between the spinnarettes. These partitions may extend the full height of the tank or mayterminate short of the bottom thereof to permit a single supply pipe, and a single overflow pipe. to takecare of the alkaline solution for the whole tank. I contemplate employing either of these constructions as may be desired, The several motors 69 are supported upon channel irons 85, which are in turn supported by brackets 86 of the frame 5 and these channel irons preferably carry housings 87, enclosing the lower portions of the motors and the current carrying wires for the same. As indicative of that fact, I have illustrated an insulating member 88 -of conventional form in Figure 1 G, the conductors being indicated at 89. The housings are also utilized as air ducts through. which fresh air may be blown to cool the motors. To this end the lower portions of the motor casings are provided with line of the guide tubes. One.

suitable openings 69 through which the air may pass as indicated by the arrows Z, upwardly around the stators and between the stators and rotors of the motors. Drop doors 87 are disposed. at intervals along the'houspresent instance it comprises a pair of yokes 93, 94. which are secured to a flexible disc 95. This is aknown form of universal joint and any known form of universal joint may be substituted therefor. The upper shaft section 91 is pinnec to a sleeve 92. A collar 93 has a press fit upon this sleeve as does the inner member 94 of an anti-friction bearing, which includes the balls or rollers 95 and the outer race 96, the latter having a press fit in a cylinder 97 The lower end of the cylinder 97 is closed by a cap 98 and the interior of the cylinder constitutes an oil chamber. A frusto-conical cylinder 99, is carried by a collar 100, which has a press fit on the sleeve 92. Openings 101 are formed through this collar adjacentthe innerface of the cylinder, these openings terminating adjacent the anti-friction elements 95. Thus, since cylinder 99 will rotate at a high rate of speed, it follows that the inclination of its walls will cause the oil to travel upwardly therealong, due to the fact that the oil is being thrown outwardly by centrifugal force: The oil that travels upwardly along the inner walls of the cylinder passes through the'openings 101 and thus the antifriction bearings are kept oiled without any attention whatever.

The cylinder 97 ispreferablysupported upon a block of rubber 102-. The inner-face of the raceway 96 is formed upon an arc struck from the center of the shaft section 91. .Thus the-motor drive is cushioned by the block 102 and is revcnted from any possibility ofbinding y the provision of the universal joint and type-of ball-bearing In Figure 5 I have illustrated means for lubricating the upper bearings of the vertically disposedmotors. As far, as the elec- 'trical features of these motors are concerned,

they are of conventional construction. However, in order to insure perfect lubrication,

particularly, of the upper bearings, I borethe motor shafts 69' longitudinally, as indi cated at 110. An oil well 111 is formed in a. cap 112,adapted to be screwed in the lower end of the motor casing 113,. The lower end of the shaft 60 is supported upon a thrust bearing 114: of conventional form and the upper end of the shaft has its hearing in-a bushing 115 of any suitable metal. A tube 116 depends into the oil well 111 and its length includes an outwardly flaring, in verted, frusto-conical portion 117. Since the shaft 69 and the tube 116 rotate at a high rate of speed it follows-that the oil within the tube and shaft will be thrown outwardly by centrifugal forceand the shape of, the

' part 117 is such as to induce an upward flow .of the oil through the bore 110 of shaft 69. 'At its upper end this bore is in communication through a transverse port 118 with a spiral groove'119 formed inthe outer face of the shaft. which groove. leads the oil up to the top. of and along the whole length of the bearing sleeve 115. The lower bearing 120 as well as the thrust bearing 114, are

sufficiently lubricated :by being disposed in the oil chamber 121. However, the lower bearing may be lubricated in the same mannor that the upper bearing. is lubricated by forming a spiral groove 119 about the motor shaft, opposite the lower bearing 120 and con-' necting said groove by a port 119 with the bore 110 of the shaft, at-a point beneath a baffie plate 119.

Any oil which finds its way downthe outside of the shaft 69? from groove 119 enters the cup 122 which is secured to and rotates with the shaft 69 and when enough oil has been collected in this cup it is thrown outwardly by centrifugal force from the upper edge of the cup at 123 and finds its way backinto the oil chamber 121 through conduits- 124 and'125.

It is to be understood that the invention is not limited .to the precise construction set' forth but that it includes. within its purview whatever changes fairly come within either the terms or the spirit of the appended claims.
